The purpose of this project was to evaluate working parameters for the corona spinneret to create electrospun fibers/ fiber mat. This project was set-up using a Box-Behnken design of experiment. The working parameters were investigated by performing the electrospinning process, altering the working conditions, collecting the electrospun fibers. The scope of this project includes three primary operational conditions: distance between the spinneret and the collection plate, the viscosity (weight percent) of PEO in the spinning solution and the weight percent of NaCl in the spinning solution. The distance between the spinneret and the collection plate were varied to 18 cm, 24.5 cm and 31 cm. The weight percent’s of PEO in solution that were used were 3, 4 and 5 percent. The weight percent’s of NaCl used were 0, .05 and .1. It was found that at 18cm, the apparatus, generally, had difficulty creating electrospun fibers and resulted in large pools of liquid on the collection plate. At 31 cm, the apparatus had difficulty generating fibers as well. At the 24.5 cm, distance the apparatus produced fibers. It was found that adding NaCl in either concentration negatively impacted the apparatus’ ability to produce electrospun fibers.
